This invention concerns curtain heading tape.

It is known to produce curtain heading tape of various widths, andrecently in order to obtain pronounced pleating effects in depth in thecurtain it has been proposed to use curtain heading tape of greaterwidths than was the practice in the past. Such tapes have been providedwith pockets on one face or both faces of the tape, and draw cordslocated adjacent the edges of the tape. In such a construction, it isfound difficult to produce even pleating across the width of the tape,in view of the spacing between the cords, and in practice it is foundnecessary to pleat the tape initially by tightening the cords and thenhaving produced initial pleating to straighten the pleats so that theylie transversely of the tape. The natural tendency is for the tape topleat extremely unevenly across its width. In view of this disadvantage,wide tapes of the kind which when used can produce very attractiveeffects have not been used to the extent that it was thought possible.The object of the present invention is to produce a curtain heading tapeof substantial width, in which the disadvantages referred to above canbe overcome, or at least substantially reduced.

According to the present invention, a curtain heading tape having spacedpockets on one or both faces is characterized in that there are at leastthree draw cords in the tape, the said draw cords passing through thebody of the tape adjacent the edges of the pockets and at the rear ofthe pocket between its edges.

Preferably the tape is provided with a rayon weft and a cotton warp.

The invention will be described further by way of example with referenceto the accompanying drawings in which:

FIG. 1 is a front perspective view of part of a tape made in accordancewith the invention.

FIG. 2 is a rear perspective view of the tape of FIG. 1;

FIGS. 3a to 3d are diagrammatic views showing the manner of shedding foreach of the wefts and the cord separately and;

FIG. 4 is a composite diagrammatic view showing the complete tape insection.

To produce a curtain heading tape in accordance with the invention, acotton warp and rayon weft are used. The shedding of the warp is suchthat pockets 10 are produced on one face of the tape at approximately 1%inch centers. The shedding is such that between the pockets 12, the bodywarps and the pocket warps are shed together and in the pocket regionsthe shedding is such as to divide the warps into two groups. The warpdensity in the pockets l and in the body of the tape behind the pocketsis half of the density of that in the body of the tape between thepockets l0. Adjacent each selvedge and along the longitudinal centerline of the tape is provided a draw cord 1 1, these cords 1 l lying onor floated on the front face of the tape and being bound to the bodyover a distance of three picks at either side of the pockets 10. Thedraw cords 11 pass from the front face of the body to the rear face atthe edges of the pockets l0 and are bound or floated to the rear face ofthe body substantially midway between the transverse edges of thepockets 10 for two picks.

The overall width of the tape is three inches, there being a 1% inchselvedge at each side of the tape into which the pockets 10 do notextend.

To weave the tape two shuttles are used one of which weaves the body ofthe tape and the other weaves the pockets 10. The pocket weaving shuttlealso weaves, as will be explained below, over a distance of four warpsalong one side of the tape between the pockets 10. These four warps areherein referred to as pocket weft binder warps.

Referring now to FIGS. 30 to 3d and FIG. 4 it will be seen that thereare several groups of warp. There being in fact body warps 12 as shownin FIG. 3d which are woven plain weave continuously over the whole tape;pocket warps 13 which are woven plain weave for eight picks with thesecond shuttle to form the kets and are thereafter woven with the bodwarps 12 or three picks at either side of the pocket with both shuttlesand thereafter with the body warps 12, with only the body shuttle, ascan be seen from FIG. 3c. Additionally, there are pocket wefl binderwarps 14 which are woven over the pocket with the pocket weft shuttleand which at one end only of the pockets are woven continuously withboth shuttles to enable the pocket weft to be taken from one pocket tothe next without being used across the full width of the tape betweenthe pockets and without forming long floats of wefi between the pockets.In the tape being described there are in fact four such warps.

To carry out the weaving operation as described so far there are sixshafts or heald frames, there being two for the body warp 12, two forthe pocket warp l3 and two for the pocket weft binder warp 14.

The three draw cords 11 are shed by a seventh shaft or heald frame andshedding is such that the cords ll lie on the pocket side of the bodybetween the pockets l0, and are woven for three picks at either side ofthe pocket 10 by the pocket weft shuttle as it binds the pocket warp 13into the body. The cords 11, as can be seen from FIG. 3a pass from thepocket side of the tape at the edges of the pocket 10 to lie behind thebody of the tape. At the center of the pocket the cords are woven fortwo picks by the body weft, as can also be seen from FIG. 3a. The cordat one side of the tape lies alongside the innermost pocket weft binderwarp 14 as can be seen in FIGS. 1 and 2 and FIG. 4.

The lines R? on FIGS. 30 to 3d and FIG. 4 are located at the edges ofthe pockets 10 which, as can be seen from these figures, is of eightpicks width.

In use it is found that the tape described above can be evenly pleatedby pulling the three cords ll simultaneously, and the further advantageof this tape exists, when comparing it with previous tapes ofapproximately the same width, in that not only does it pleat evenlyacross its width, but by virtue of the binding in of the draw cords 11to the rear face of the body, midway between the edges of the pockets 10small reverse pleats 10a are formed along the length of the rear face ofthe body in the pocket regions, thus tend to cause the pockets to becomepartially opened and facilitate location therein of curtain suspensionhooks.

What is claimed is:

l. A curtain heading tape having a body and spaced pockets on at leastone face thereof characterized in that there is at least one draw cordin the tape, said draw cord passing through said body adjacent the edgesof the pockets and also floated on both sides of said body for aplurality of picks behind each pocket and between the edges of saidpocket.

2. A curtain heading tape as claimed in claim 1 in which the tape has acotton warp and a rayon weft.

3. A curtain heading tape as claimed in claim I in which the warpdensity in the region between the pockets is twice that of the warpdensity in the pocket faces.

4. A curtain heading tape as claimed in claim 1 in which the weave forthe pockets and the regions therebetween is plain weave, the pocketforming war s being woven with the body warps between the pockets.

5. A curtain heading tape as claimed in claim 1 in which a series ofpocket weft binder warps are provided along one edge of the tape tocarry the pocket weft from one pocket to the next.

6. A curtain heading tape as claimed in claim 1 in which the cords arefloated into the tape at each edge of the pocket by the weft of a pocketweaving shuttle, and are floated into the rear of the pocket by a bodyweft weaving shuttle.

8. A curtain heading tape as claimed in claim 6 in which the cords arefloated in for three picks at each side of the pocket and by two picksat the center of the rear face of the pocket.
